Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed June 21, 1899. Serial No. 721,330.

To all whom it may concern:

Be it known that I, EARL G. VVATROUS, a citizen of the United States of America, residing at Chicago, in the county of Cook,

' in the State of Illinois, have invented a certain new and useful Improvement in later- Closet Valves, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention has for its object thc provision of an improved slow-closing watercloset valve, adapted more especially to be automatically operated by the seat but also capable of use as a hand-operated valve. Its novelty will be hereinafter set forth and particularly pointed out in the claims.

In the accompanying drawings Figure l is a perspective view of a closet provided with my improved valve arranged to be automatically operated by the seat; Fig. 2 a detail top-plan view of the rear portion of the seat and its hinges and cooperating devices; Fig. 3 an enlarged sectional detail on the line 3 3 of Fig. 2; Fig. 4l a middle vertical section of the valve; Fig. 5 a horizontal section on the line 5 5 of Figl ll; Fig. 6 a perspective detail of the adjustable inlet valve in the supply pipe; and Fig. 7 a perspective detail of the lifting arm on the rock-shaft.

The same letters of reference are used to indicate corresponding parts in the several views.

Describing first the novel construction of the valve, and later the means for operating it, and referring more particularly to Fig. et, the main casing is composed of the middle body portion A having upon one side the pipe connection B, a cap or dome C at its upper end, and a pipe D screwed into its lower end and communicating with the closet. Within the upper part of this casing is secured an open-ended cylinder E which in the present instance is provided at its lower end with an outwardly projecting flange E which seats upon an annular shoulder formed upon the inner surface of the casing A and is confined in place by the lower end of the cap C, being clamped between said cap and shoulder when the cap is screwed into place inthe upper end of the casing A. Tight joints are insured by rubber packing rings, the lower one of which, F, will be hereafter referred to.

The provision of the separate cylinder E within the casing or cap C (instead of employing the walls of the casing as the cylinder to receive the piston, as usual) produces an annular sediment chamber surrounding the cylinder, to receive the sediment deposited by the water within the cap and prevent it lodging between the piston and cylinder walls and causing wear of said parts.

Fitting within the cylinder E and adapted to move up and down therein is a piston G having a depending` tubular stem II which carries, beneath the piston G, the main valve H which cooperates with an annular shoulder or seat I formed upon the internal surface of the casing A. The main valve I-I may in the present instance be said to be composed of three parts, a disk a formed integral with the central tube I-I and having an up-turned liange Z9, a rubber ring c fitting against the under side of the disk o, and a nut CZ screwed upon the threaded exterior of the tube II, beneath the ring c and serving to clamp the latter between the nut and the under surface of the disk a. The nut (Z has a` smooth periphery adapted to pass freely through but approximately fit the central hole through the valve-seat I. This particular construction of the main valve I-I is not essential to the main features of my invention.

Screwed upon the lower end of the pistonstem or tube II is a flanged nut or disk J, constituting a supplemental valve for a purpose hereafter explained.

Extending vertically through the tube I'I is a smaller tube II, open at its extreme lower end and partially closed at its extreme upper end by a screw L provided with a groove e constituting a minute by-pass or vent between the interior of the tube K and the interior of the cap C above the piston G. Carried by the lower end of the tube K is a circular casting M having in the present instance a convex upper surface connected by an integral stem M with the lower end of the tube K, the internal bore of the latter being extended downward through the stem M and member M. The stem IJ terminates in a shoulder f a short distance beneath the lower end of the outer one of the two oentral tubes Il, so that the inner tube K and parts carried by it are free to move up and down a limited distance independently of the tube I-I and parts carried by it. The stem M is provided with a recess, Fig. 7,

'lid

engaged by the end of an arm 0 fast upon a rock-shaft l) having a suitable bearing in the casing as hereafter described. llpon rocking the shaft P in a direction to lift the arm O the latter will lift the stem M and parts carried by it until the shoulder f contacts with the lower end of the larger tube l-l, whereupon further movementof the rock-shaft l and arm (l will lift the tube fl and parts carried by it, including the main valve and the piston G.

The tube K does not fit tightly within the tube H, but on the contrary there is a passageway between them, and at its eX- treme upper end of the tube l passes" through a hole L in the top of the hollow piston Gr, which hole is considerably larger than the tube, to afford free passage between them. Secured upon the upper end of the tube K, in the present instance byy being screwed upon the screw L, is a nut Q constituting a valve and adapted to rest, in its lower position, upon a rubber washer R upon the upper surface of the piston Gr and close the passage-way around the upper end of the tube K. rlhe latter opens into the interior of the hollow piston G by ports e'.

rlhe operation of the parts under the above described construction, assuming the interior of the casing A above the main valve, to be filled with water under pressure, and the cap C to be filled with water or water and air is as follows: Upon rocking the shaft P in a direction to swing its arm O upward the latter will at the beginning of its movement lift the inner tube K independently of the tube lvl, which will serve to raise the valve Q at the upper end of the tube K from its seat upon the top of the piston G, thereby placing the interior of the cap C in free communication with the tube lvl and thence downward through the saine to the interior o f the casing beneath said tube. ln order to prevent the closing of the. annular passage between the stem H and tube K when the shaft l? is operated as described, l provide a groove or grooves m in the stem M through which the water may pass from the interior of the cap C as just stated, notwithstanding the fact that at this time the top of said stein M is in contact with the lower end of the stein ll. The provision thus made for the escape of the water within the cap C will permit the piston G to be lifted in its cylinder E by the further upward movement of the arm G and inner tube, the shoulder f at the lower end of the latter enO'aOino' the lower end of the tube b b b H as before explained. A full stroke of the shaft P and arm 0 will carry the tube H upward to position for the upper edge of the flange Z) of the disk a to contact with and bear against the under side of the packingring F whose inner edge projects inward beneath the piston G. This will lift the main valve from and carry it entirely above its seat l and bring` the disk J upon the lower end of the tube H into the circular opening in the seat l, which it snugly lits. So long as the. arm O is held in elevated position, therefore, the water supply will be cut olfl from the closet (and also from the chamber above the piston) by the disk J fitting within the valve-seat l, excepting the small quantity of water permitted to pass tlu'ougli the openingduring the interval between the lifting of the main valve from its seat and the bringing of the disk el into the same. `llllln-Bn the rock-shaft P and the arm t) are now released the inner tube K and parts carried by it will .instantly drop downfard until the valve Q upon the upper end of the tube K rests upon the washer lt upon the top of the piston, thus cutting olf the free communication between the cap C and interior of the piston G and tube lvl'. its the tube H and parts carried by it (including the piston G) then begin to descend the partial vacuum created within the cap C by the descent of the piston G in the cylinder E will retard the downward movement of the parts, and they will be permitted to move downward only so fast as water or air can pass from the interior of the inner tube K to the cap C through the groove e in the screw L. By regulating the size of this by-pass by adjusting the screw L, (the groove c being tapered) the closing movement of the valve can be gaged as desired.

lt will be understood that when the main 'alve is closed as in nig. the interior of the casing It, between the upper side of the main valve and its seat, and the under side of the piston G, is filled with water under pressure admitted through the pipe-connertion B and the coupling B by the open valve C, and that when the main valve is lifted from its seat water under pressure rushes downward through the open valve seat and fills the lower part of the casing A and pipe D, the escape of the water to the closet through the pipe D not being as free as its admission through the valve-seat when the valve is lifted. lWhenever the valve is opened, therefore, the consequent upward movement of the valve and piston will displace part of the water in the cap C, which displaced water will escape downward into the discharge chamber through the tube H, inasmuch as the valve Q, has been lifted from its seat so as to afford a free communication of the water thereat. it the closing movement of the main valve and llO liti

pass upward into the cap C as the main valve slowly descends upon its seat. After the valve is closed and during the time it remains closed, therefore, the middle portion of the main casing A will remain filled with water and the cap C will remain partially filled with water. The main valve remains seated inasn'iuch as the area of such valve is larger than the arca of the cylinder G. Consequently there will always be a greater pressure exerted on the main valve in order to force or rather hold it to its seat.

The purpose of the flange 7) projecting upward from the disk fi of the main valve and adapted to seat, at the end of the upward movement of the parts, against the packing-ring F, is to form a tight joint at that point and thereby `prevent the under pressure leaking past the piston G within the cylinder E during the time the main valve is lifted from its seat, which might otherwise occur and produce backpressure upon the upper end of the piston G. This provision may be omitted where the valve is used as a hand-operated alve, as may also the disk .l upon the lower end of the tube H, since in such event the main valve is simply lifted from its seat by means of the operating handle and at once released and there .is no occasion for cutting oft' the flow of water to the closet while the main valve is open.

The circular member lvl carried by the lower end of the inner tube K approximately (but not snugly) tits the internal bore of the extreme lower end of the valve casing A and pipe D, Fig. l, but the casing A flares outward above its lower end so that when the parts are lifted by rocking the shaft P and swinging upward the arm O there will be a large free passage within the casing A around the member M. As the parts descend, however, and the main vale approaches its seat, the downward movement of the member M through the inwardly contracting lower end of the casing` A will gradually reduce the size of thel passage around said member M and restrict the flow of water from the interior of the casing A. to the pipe D and closet. As the lower portion (Z of the main valve enters the seat l the water within the casing beneath the valve will be trapped as it were between said valve and the disk lll, and as the valve is of larger diameter than the disk it follows that the parts can therefore descend only so fast as the escape of the water downward around the disk M will permit. The provision of this construction and arrangement of the parts prevents the main valve being forced suddenly against its seat at the end of its closing movement and the consequent hammering which might otherwise occur.

The chamber within the cap C of the caswatcr ing constitutes what may be called the retarding chamber, the space within the casing [t opposite the pipe-connection B (between the main valve and under side of the piston) constitutes the inlet chamber, and the space beneath the main valve and its seat, within the casing, constitutes the discharge chamber; and it will be seen that the retarding chamber is in communication by central supply and exhaust passages with the discharge chamber in the lower part of the casing, the water in the retarding chamber escaping downward through said central passages as the main valve and piston are lifted, and passing upward through the supply passage, from the discharge chamber to the retarding chamber, as the piston descends and the main valve closes. When the valve is closed the water pressure is entirely cut off from the retarding chamber and the latter is in communication (by the minute supply passages or by pass) with the atmosphere, through the discharge chamberand closet. These conditions are novel in valves of this character, and are of importance in the operation of such valves. Owing to the fact that the retarding chamber has no communication with the inlet chamber or water-supply (except through the discharge chamber) and owing to the fact that the water pressure in the discharge chamber is gradually reduced as the main valve approaches its seat and cuts off communication with the inlet chamber it follows that there is no considerable pressure in the retarding chamber during the closing movement of the valve, and the result is that the latter moves to its seat slowly and gently, without any sudden shock or jar or hammering at the end of its closing movement, as is likely to occur where the supply passage or by-pass for the retarding chamber communicates directly with the inlet chamber or pressure supply and the valve closes under pressure in the retarding chamber, is common in other valves of this character.

A further novel feature of my new valve relates to an adjustable throttle-valve interposed in the supply pipe, for regulating or entirely cutting ofi' the supply of water admitted to the main valve of the closet. As before explained the main casing A is provided upon one side with the pipe connection B which coupled by a union nut l with a short pipe section ll interiorly threaded at its opposite end to be screwed upon the. exteriorly threaded end of the supply pipe. A, suitable packing ring is interposed between the parts and ll to form a tight joint, while the member B is provided at I its inner end with an inturned flange adapted to form a seat for a valve C having a convex outer surface from whose center projects a threaded stem C passing through a threaded hole in a bridgeD extending across ll (l the interior of the member B, The valve C provided upon its opposite ede'es with slotted ears a" which engage ribs o formed upon the inner surface oit the pipe connection l and serve to prevent rotation et the Valve C and to guide it in its inward and outward adjustments. ln the drawing` the valve C shown in a position intermediate its closed position and its maximum open position. ly slightly loosening the coupling` nut B, .so as to permit independent rotation of the members B and B, and turning the member B in one direction or the otherj the valve C will be moved toward or from its seat, to reduce or increase the size of the passage around it, as may be desired. in initially setting or adjusting the 'valve C the member B will be turned as above in dicated and the coupling nut B then tightly screwed up again; but a'ter the main valve has been connected to the supply pipe and to the closet the practice will be to disconnect the Valve Yfrom the closet and loosen the coupling` nut B and then turn the whole valve in one direction or the other relatively to the fixed member B Screwed upon the supply pipe, and after the Valve C has been adjusted to the desired position the main valve will be reconnected to the closet and the coupling nut B tightened again.

d tight joint is et'tected and mzrintained between the rock shaft l and the valve casing; by the novel means ,shown more particularly in Fig. 5. )is there shown the rockehatt is eurroimded by a bushing` ll slipped over the shaft from its opposite end and screwed into the :asing' A, The rock-slnn'f't l) is prorided with a shoulder c between which and the inner end et the lniehing` P is coniined a paclingaing CZ', and the rocle Shaft is constantly pressed outward and its Shoulder c toreed tightly against the paching-ring` d by t spring e confined between the inner end or' the rocketshatt and the opposite wall of the casing. ln the present inetance this springl a coiled fpring held in pla e at one end by engaging a Stud termed upon the inner 'face oit the casino` and having` its opposite tree end projected centrally trom the coil and engaging a tapered recess termed in the end oit `the roele eha'tt. this particular construction and ar rangement et the spring' c and its engagement with the rock-shaft lacilitatee the ready assemblage and Self-adjustment ot the parts, but may be varied without losing` the main ad Yentagee of this feature et my inrentioin which consist in providing' and readily maintaininga tight joint by the yii-lding' pressure ot the shoulder e againstthe packing-ring d without produeinpI objectionaole t'riction, as is the case where an ordinary shitting-box ie employee.. particularly important where the Valve is to This is i be automatically operated by the seat, in the .manner to be now explained.

)is shown in F l the rock-shaft l has secured to :nd projecting forwardly from its` outer end a short arm lt connected by a depending' adjust-able link lt with the rear end ot an n lt, Fig, 2, formed upon and projecting rea wardly from. a sleeve S, Figs. l, and which eleere has bearings at its opposite ende in vertical :supports S secured at 'their lower ende in the closet T. Extend ing' longitudinally through the sleeve S is a rod ll which is surrouinled at one end by a coiled spring` U connected at one end to the rod and at its opposite end projecting therefrom and confined in a recess at g in one ot the supports lil. )rt ite opposite end the rod U is exterimfly threaded and extends through a threaded hole in the otherwise dosed end or" the sleeve upon its outer end a loch-nut V engaging the end oit the sleeve S and by tightening which the rod ll and sleeve are locked together. The rod U has a nick termed in its end tor the recc-ption of a screw-driver eo that by loosening the lock-nut V the rod may be turned in one direction or the other to regulate the tei tion oit the spring,v U.
